Dormer Pramet A225 1/16 Inch x 3/16 Inch HSS BS 60 DEG CENTRE DRILL BS 328

The Dormer Pramet A225 centre drill (1/16 in x 3/16 in) is a premium, double-ended HSS tool designed to create accurate centre holes on shafts. With a 120° pilot and a 60° cone, it guides subsequent drilling for secure holding and repeatable alignment. The bright finish reduces sticking and residue build-up, and the tool can be used on steel, aluminium and stainless steel. Compatible with both CNC and conventional machines, this drill delivers dependable performance in busy workshops and precision tasks.

• Double-ended design for productivity: Two drilling ends provide increased productivity and economy by reducing downtime and extending tool life between changes.
• Precise center-hole geometry (120° pilot / 60° cone): Ensures accurate, well-aligned centre holes that secure shafts and improve downstream bore accuracy.
• Premium HSS with bright finish: Drills a range of materials including steel, aluminium, and stainless steel, with a bright finish that minimizes sticking and promotes clean chip flow for smoother starts and longer edge life.

This center drill helps you optimize setup time and achieve consistent, high-quality hole starts. By delivering reliable centre holes on CNC and manual machines, it reduces rework, improves runout control in fixtures, and supports faster part throughput without sacrificing accuracy or surface finish.
